In an embodiment, an actuator or circuit includes elements moveably coupled via bearings positioned between curved grooves. The bearings and the curves may exert a restorative force to return the elements to an original position after movement and may be spherical, cubic, cylindrical, and/or include gears that interact with groove gears. In some embodiments, an electrical coil may be coplanar with a surface of an element and a hard magnet may be positioned in the center and be polarized to stabilize or destabilize the element with respect to another element. In various embodiments, a magnetic circuit includes an element with an electrical coil wrapped in multiple directions around the element. In some embodiments, an actuator includes attraction elements and exertion of force causes an element to approach, contact, and/or magnetically attach to one of the attraction elements.

A magnetic circuit, comprising: a moveable bar element that includes at least a first hard magnet and a second hard magnet; anda fixed bar element that includes an electrical coil structure wound around the fixed bar element, wherein a first section of the electrical coil structure is wound in a first direction around a first area of the fixed bar element, and a second section of the electrical coil structure is wound in a second direction around a second area of the fixed bar element;wherein the moveable bar element is moveably coupled to the fixed bar element. 13. The magnetic circuit of claim 12, wherein the first direction and the second direction are opposing directions. 14. The magnetic circuit of claim 12, wherein the electrical coil structure includes a middle section where the direction of winding is changed between the first direction and the second direction. 15. The magnetic circuit of claim 14, wherein the middle section is attached to the fixed bar element. 16. The magnetic circuit of claim 12, wherein the moveable bar element further comprises at least one soft magnet wherein at least one of the first hard magnet or the second hard magnet is positioned between the at least one soft magnet and the fixed bar element. 17. The magnetic circuit of claim 12, wherein the moveable bar element is moveably coupled to the fixed bar element by at least one bearing that is positioned between at least one first groove and at least one second groove. 18. The magnetic circuit of claim 12, further comprising an additional moveable bar element separated from the moveable bar element by the fixed bar element wherein the additional moveable bar element is moveably coupled to the fixed bar element and includes at least a third hard magnet and a fourth hard magnet. 19. An actuator, comprising: a fixed body element, including at least one first groove and at least one electrical coil;a moveable body element, including at least one second groove and a first and second hard magnet; andat least one cube bearing positioned between the at least one first groove and the at least one second groove that separates the moveable body element from the fixed body element;wherein the moveable body element is magnetically attracted toward the fixed body element and at least one of the at least one first groove or the at least one second groove is curved such that applying a lateral force to the moveable body element causes the at least one cube bearing to move the moveable body element laterally with respect to the fixed body element. 20. The actuator of claim 19, wherein ceasing to apply the lateral force causes the at least one cube bearing to move the moveable body element laterally with the fixed body element to return to an original position.
